Effect of Water Suppression and Metabolite Cycling on Quantification of 1H MRS Spectra in the Human Brain at 3 Tesla

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose This study investigates the effect of VAPOR water suppression and metabolite cycling on metabolite quantification and macromolecules in proton magnetic resonance spectroscopy. Methods Single‐voxel semi‐LASER spectra (TR/TE = 3000/28 ms) and metabolite‐nulled spectra (macromolecules) were acquired in five healthy subjects in the ...

Preclinical 1H MRS Study of a Porcine Model Shows Evidence and Mechanisms for Acute Neuronal Injury in Neonatal Cardiopulmonary Bypass (CPB) Surgery

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Congenital heart disease affects 1% of US births, with some infants requiring cardiothoracic surgery under cardiopulmonary bypass (CPB). Optimal surgical parameters to minimize neuronal injury are unknown. We used serial 1H MRS in a neonatal CPB porcine model to assess acute neuronal damage and associated injury mechanisms.

The Impact and Reliability of Tissue Segmentation on In Vivo Magnetic Resonance Spectroscopy Metabolite Quantification

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Quantification of metabolite concentrations using MRS requires tissue‐dependent signal corrections. Accurate estimation of voxel tissue composition is therefore essential. Commonly used brain tissue segmentation tools differ in their algorithms and implementation, potentially introducing variability in MRS‐derived concentration ...

Trends and Racial/Ethnic Disparities in Pharmacologic and Surgical Management of Treated Female Patients With Urinary Incontinence

Neurourology and Urodynamics, EarlyView.
ABSTRACT Background The current literature summarizes the trends in the surgical management of stress urinary incontinence (SUI) and not the general trends of management for all UI types in the US. Additionally, recent evidence on racial and ethnic disparities in UI related surgical utilization is limited. Objective To describe the currently prescribed

Adipose‐derived and bone marrow aspirate concentrate injections for osteoarthritis: A scoping review

PM&R, EarlyView.
Abstract Background Osteoarthritis is a leading cause of disability worldwide, and cell‐based treatments including adipose‐derived and bone marrow aspirate have been sought by the lay and medical community as treatment options. Objective To perform a scoping review of published literature on cell‐based injections allowed by the U.S.

A Statistical‐Process Hybridized Approach to Modeling Permafrost Distribution in a Boreal Wetland Ecosystem, Whatì, NT, Canada

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT High‐resolution mapping of permafrost in ecologically and topographically complex landscapes remains a major challenge. Existing models of permafrost extent often rely on equilibrium assumptions, which can misrepresent conditions in regions where permafrost persists largely due to ecosystem structure.
